Generator

The VXL Direct Digital Synthesizer (DDS) is an IP core for digitally creating arbitrary waveforms and frequencies from a single, fixed source frequency. This DDS system takes a constant reference clock input and scales it down to a specified output frequency sampled at the reference clock frequency. This method of frequency control makes the IP core ideal for systems that require precise frequency sweeps like Radars.

Overview:

The VXL Direct Digital Synthesizer (DDS) is an IP core for digitally creating arbitrary waveforms and frequencies from a single, fixed source frequency. This DDS system takes a constant reference clock input and scales it down to a specified output frequency sampled at the reference clock frequency. This method of frequency control makes the IP core ideal for systems that require precise frequency sweeps like Radars.

Features:

Implemented using Piecewise Quadrature Sine Interpolation (PQSI) algorithm

Sixteen segments per quadrate

1024 points per segment

Very low memory requirements of 704 bits

User selectable output resolution of 12 to 20 bits

Pipeline delay of 16/17 clocks for signed/unsigned output

FCW (Frequency Control Word) resolution of 16 to 32 bits

Low SFDR (Spurious Free Dynamic Range), better than 96 dBc for output frequency range of 0.15 fclk to 0.20 fclk

Key Benefits:

Low memory requirements

High speed capabilities

Technology independent IP core

Highly optimized design with minimum usage of target device resources

Parameterized HDL design

Easily modifiable to meet specific client requirements
